had a look at getting Dynamic User Tracking working on our edge switches. works no problem on 2960 switches (using 122-52.SE IOS) - can't get it working on 2950 switches (tried a few IOS revs including latest). the snmp traps are sent ok by the 2950 and are received by LMS but they are dropped because of 'Security' - see below for macuhic.log and the UT debugging console. i've disabled "validate trap source" under Dynamic UT Config but the traps from the 2950s are still dropped becuse the switch IP is 'illegal' (the 2950s and the 2960 are all managed ok by LMS). what does the LMS log mean by illegal?

working ok now - the changes i was making in "validate trap source" under Dynamic UT Config weren't having any effect. Rebooted server and now my switch IPs are 'legal' and dynamic UT working fine as well.
